Specicaton of Ietters Patent.

Application led Apri1'3, 1916. Serial No. 88,734.

To all/whom z't may concern:

Be it known that I, AUSTIN JOHNSON, a citizen of the United States,residing at Grand Ledge, in the county of Eaton and State of Michigan,have inventedl a new and useful Improvement in Pumps, of which thefollowing is a specification.l

My device relates to pumps and more'particularly to that kind of pumpsadapted to be inserted in the casing of drilled wells, and'in which athree-way device is employed for the purpose of permitting water to flowout of a spout located at or near the pump, o1' if desired,-t0 cut ofi'the Water from the spout and force it through. pipes to a tank or anyother desired locality. Its main purposes are to make a device thatshall be easy to install, maintain and repair without digging a pit downto the level of the three-way device, and that shall also provide propermeans for the prevention of freezing and the drainage of surplus water.

I attain these purposes by the means shown in the accompanying drawingsin which Figurevl is a vertical section ofl a pump in which my device isemployed, the

lower cylinder being omitted,` as it may be of any ordinary constructionand forms no part of my present invention; Fig. 2 is a detail showing amodified construction of the drainage device.

Referring more particularly to the drawings, 1, is the outer well casingproper of the well itself in which the device is mounted; 2 is a pipeconnecting the upper cylinder 3 with the lower cylinder and 4 is thepump rod extending from the pump handle 5 through the upper plunger 6,to the lower plunger; these parts of the pump are substantially the sameas are employed in ordinary differential cylinder force pumps and may bemodified in any way without departing from my invention.

My device proper consists'of a pipe 7, somewhat smaller in externaldiameter than the casing 1. This pipe is provided with a right handedscrew thread at one extremity and a left hand at the other. A head 8 isadapted to screw on the lower extremity of the pipe 7 and is providedwith springs 9, adapted to engage the inside of the casing 1. A secondhead 11 is screwed on the upper extremity of the pipe 7, and rubberpackings 10 and 12 surround the pipe 7, immediately in contactrespectively with the heads 8 and 11. A grating 13,

wedge shaped at its two extremities, is

4mounted on theoutside of the pipe 7 in such oppositey direction, thepressure on the packings .will be released and the device may be readilywithdrawn through the top of the casing 1.A Water openings 14 are formedin the side of the pipe 1 between the packings 10 and 12 so as to permitthe water entering the pipe 7 to escape into the space between the pipe7 and the casing 1, and thence through the opening 15 into the pipe 16through .which itis carried to any desired locality. A second pipe 17extends from the head 11 upto and into the base of the pump; this pipeis practically an extension of the pipe 7. :The upper cylinder 18 isconnected by a pipe 19 with the upper extremity of the pipe 17, alongscrew 20 being employed for purposes' of adjustment as will be morefully explained farther on. The lower extremity of the upper cylinder 18is closed by a packing end 21, provided with passages 22, 'adapted toengageV with upper and lower seats 23 and 24 respectively. For thepurpose of drainage and air 'circulation a pipe 25 opens into the outercasing above and below my device serving to permit the circulation ofAair into the casing vo-f the well and also to drain awaywater from thatpart of the outer casing above my device. This pipe is of very smallldiameter. In the large sizes, where the outer casing is of sufficientdiameter," the pipe 25 may be mounted inside the outer casingas shown inFig. 2, but its operation is identically the same in the two cases. 26is the spout of the pump and opens out of the pipe 17 or, lif desired,out of the base of the pump in such manner as to connect with thepipe17. Forl the purpose of connecting the pipe 16 with the casing l, apipe saddle 27, is secured in anyV desired manner to the outside of thecasing 1 and prevented from leaking by packing 28. The pipe 2 isextended upward through the head 8 inside of the pipe 7 and has itsupper extremity formed into a seat at the head 21.v

The operation of my device is as follows: in order to mount my device inthe well, it

is lowered into the outer casing and the upper extremity of the pipe 17is attached to the body or base of the pump. The pipe 17 is thenrevolved in any desired manner, preferably by turning the pump body. Thehead 8, however, is held stationary within the casing by the springs).rlhe effect of this is to screw the head Steward the upper extremity ofthe pipe 7 and at the same timethe upper head 11 downward toward thelower extremity of the pipe 7, and thus force the vwedge shapedextremities of the grating 13 under the packings 10 and 12 and expandthem against the inside of the casing 1 so as to entirely shut off thespace inside of the casing 1 and outside of the pipe 7 between thepackings so as to form a chamber between the two.

Suppose now it is desired to draw water through the spout 2G. The pipe19 is turned by a head 2f) or any suitable manner so as to force thehead 21 downward against the lower seat 2li. frs the water rises intothe pipe 2 from the lifting cylinder below it can not enter the space 30between the pipe 7 and the casing 1, being shut off by the head 21, andtherefore rises through the passages 22 in the head 21 and flows upwardinto the pipe 17 outside of the upper cylinder and the pipe 19 andescapes through the spout 2G. 1f it is now desired to shut oli the spout26 and discharge the water through the pipe 16, the pipe 19 is screwedupward by the head-29 so as to bring the head 21 against the upper seat;'the water is thus prevented from escaping from the pipe 27 but flowsoutward over the upper edge of the seat 2st around the pipe 2 into thespace 30, thence outward through the openings ld, the grating 13 and thesaddle 27 into the pipe 16.

I claim as my invention and desire to secure by Letters Patent:

1. rlhe combination in a pump provided with upper and lower cylindersand adapted to be inserted in the casing of a drilled or bored well, anda pipe connecting said cylinders, of' a water chamber surrounding saidpipe and provided with screw threads at its extremities; mounted on eachof said threaded extremities, the 'lower extremity thereof beingprovided with means for engaging with the inner side of the well casingso as to prevent revolution; packing rings mounted near the extremitiesof said water chamber and adaptedv to close the space between saidchamber and said well casing; a perforated a collar operatively collarvsurrounding said water chamber bctween said packing rings and providedwith wedging extremities adapted to force said ring into engagement'withsaid well casing, and means for revolving said water chamber within saidcasing.
